Abstract: The methods and application of process oriented virtual
assembly modeling, which integrate the assembly modeling and assembly
simulation in virtual environment are presented. Process oriented
virtual assembly modeling not only fulfils the assembly relationship
modeling, but also realizes the creation and simulation of the assembly
process, thus, assembly modeling can be promoted from result oriented
modeling to process oriented modeling in virtual environment. While the
designer performs assembly modeling operation in direct 3D interaction,
the assembly relationship recognition is devised to capture the assembly
design intention automatically, the constrained movement of the
assembling part is used to obtain the assembling part’s assembly path
and final position in assembly, and the reuse of virtual assembly
modeling process information is also adopted to support the virtual
assembly planning. The methods are implemented in the development of
VIRDAS (Virtual reality design and assembly system). The experiment
shows the methods can promote the quality and efficiency of virtual
assembly modeling rapidly.
Key words: Virtual design Virtual assembly Assembly modeling
